To characterize blood monocyte subsets in patients with different degrees of carotid atherosclerosis and pathological carotid plaque neovascularization. ⋯ In this pilot study classical monocytes (Mon1) represent the only monocyte subset predictive of the severity of carotid and systemic atherosclerosis, such as carotid intima-media thickness, degree of carotid stenosis, and presence of carotid intraplaque neovascularization.

Treatment with tumour necrosis factor antagonists (anti-TNF) has been recognized as a risk factor for tuberculosis (TB) reactivation. Our aim was to evaluate risk of TB reactivation in rheumatologic and non-rheumatologic diseases treated with the same anti-TNF agents with and without concomitant therapies. ⋯ TB risk with anti-TNF agents appeared to be increased when these agents were used in combination with methotrexate or azathioprine as compared with monotherapy regimen. TB risk seemed to be higher than placebo, even when monotherapy is prescribed.

Systematic reviews and meta-analyses for more profitable strategies in peripheral artery disease.
In the peripheral arteries, a thrombus superimposed on atherosclerosis contributes to the progression of peripheral artery disease (PAD), producing intermittent claudication (IC), ischemic necrosis, and, potentially, loss of the limb. PAD with IC is often undiagnosed and, in turn, undertreated. The low percentage of diagnosis (∼30%) in this setting of PAD is of particular concern because of the potential worsening of PAD (amputation) and the high risk of adverse vascular outcomes (vascular death, coronary artery disease, stroke). ⋯ Innovative imaging techniques are needed to identify PAD subjects at the highest vascular risk. Whether IC unresponsive to physical exercise and smoking cessation identifies those with a heritable predisposition to more severe vascular events deserves to be addressed. Devising ways to improve prevention of vascular events in patients with PAD implies a co-ordinated approach in vascular medicine.

Biomarkers of T-cell receptor excision circles (TRECs) and immunoglobulin κ-deleting recombination excision circles (KRECs) reflect naïve T and B cell emigrants. This study assessed the biomarkers in patients with primary immunodeficiency diseases (PIDs) to determine the lymphocyte output disturbance and the correlation to lymphocytes. ⋯ This study validates that low TRECs and KRECs values reflect low naïve T and B lymphocytes in 'combined immunodeficiencies' and in some CVID patients with the potential to develop the CID phenotype.
